The mileage of electric vehicles is one of the important criteria for consumers to measure the quality of electric vehicles. As we all know, the lithium battery of electric vehicles plays a decisive role, so what should be paid attention to in the maintenance of lithium batteries of electric vehicles? Ace Battery summarizes six tips for lithium battery maintenance for reference:
1. Lithium batteries are strictly prohibited from losing power when stored
When lithium batteries are stored in a depleted state, sulfation is prone to occur, and lead sulfate crystals adhere to the plates, blocking the ion channels, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-loss state, the more serious the battery damage. Therefore, when the battery is not in use, it should be recharged once a month, so as to keep the battery in a healthy state.
2. Periodic inspection of lithium battery
If the continuation mileage of an electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has broken grids, softening of the plates, and falling off of the active materials of the plates. At this time, you should go to a professional battery repair agency for inspection, repair or matching. This can relatively extend the life of the battery pack and maximize cost savings.
3. Prevent high current discharge of lithium battery
When the electric vehicle starts, carries people, or goes uphill, please use the pedals to assist, and try to prevent instantaneous large current discharge. High current discharge can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plate.
4. Correctly grasp the charging time of lithium battery
In general, different types of lithium batteries are charged at night, and the average charging time is 8 hours. It is best to charge the battery once when the depth of discharge is 60%-70%. In actual use, it can be converted into riding mileage. Necessary charging is performed according to the actual situation to prevent harmful charging.
5. To prevent lithium battery exposure
The high temperature environment will increase the internal pressure of the lithium battery and force the battery pressure limiting valve to automatically open. The direct consequence is to cause a decrease in battery activity, accelerate the softening of the plates, and cause fatal damage such as shell heating, shell bulging, and deformation during charging.
6. Prevent the plug from heating when the lithium battery is charged
The loose output plug of the charger and the oxidation of the contact surface will cause the charging plug to heat up. If the heating time is too long, the charging plug will be short-circuited, which will directly damage the lithium battery and cause unnecessary losses.
